ITU-T G.774 (02/2001)

This Recommendation provides an information model for the synchronous digital hierarchy (SDH). This model describes the managed object classes and their properties that are useful to describe information exchanged across interfaces defined in ITU-T M.3010 telecommunications management network (TMN) architecture. This Recommendation specialises the generic object classes of ITU-T M.3100 to provide management information specifically for the SDH.
